To all whom it may concern.-

Be it known that I, CARL PoHL1'r,a citizen of the German Empire, residing at Essen Germany, have invented certain new and useful Improvements in Safety Devices for Breech Mechanism of Ordnance, of which the following is a specification.

This invention refers to a safetydevice for breech mechanism of ordnance. Safety devices for guns have frequently been so arranged as not only to prevent accidental firing of the gun, but likewise to guard against accidental opening of the breech; but all these devices require setting by hand, which may frequently be neglected when limbering up, and the breech may then he accidentally opened while driving.

The object of my invention is to produce a safety device which automatically locks the breech-handle against turning as soon as it has been turned to lock the breech and to hold the handle locked until the trigger is pulled or the safety device is released by hand.

For this purpose the invention consists, essentially, of a spring safety-bolt inserted into the breech-block and providedwith a lug adapted to engage a corresponding recess within a flange of the breech-handle, so as to prevent turning of the handle, combined with means to automatically disengage the lug from the flange when pulling the trigger and also to release it by hand.

The nature of my invention will best be u nderstood when described in connection with the accompanying drawings, in which Figures 1 and 2 are side elevations of a horizontal-wedge breech mechanism, showing the breech-handle secured in Fig. 1 and released in Fig. 2. tion on the line III III, Fig. 1. Fig. 4 is a horizontal section on the line IV IV, Fig. 2. Fig. 5 is a detail view of the safety-bolt.

Similar letters of reference designate correspondin g parts throughout the several views of the drawings.

' In the figures the letter E designates the breech-block; B, the actuating-handle of the Fig. 3 is a horizontal sec-' locking-screw; (J, a flange on the lockingscrew; D, the trigger pivoted on the pin 6 and provided with the eye f for the lanyard and with a downwardly-projecting cam d.

A is thesafety-bolt, embodying the hollow shank h, the safety-lug a, and the lateral too 0, with the push-button b. This safety-bolt A is adapted to be inserted into a corresponding recess of the breech-block E, together with a spring g, which tends to force the bolt outward against the flange C, which flange has a recess for the lug a. The parts are so proportioned that the lug enters the recess of the flange 0 when the screw is turned so as to lock the breech-block and when the trigger is in the position shown in Figs. 1 and 3. IV hen, however, the trigger is turned to the position shown in Figs. 2 and 4., the cam d, bearing against the too 0, pushes the safetybolt A inward, thereby disengaging the lug a from its recess in the-flange 0, so that the locking-screw is free to be turned by the actuating-handle B. The safety-bolt A may also be pushed back by hand by pressing against the push-button b. It is evident that any accessible part of the toe 0 may serve as a push-button. Thus when the parts are in the positions shown in Figs. 1 and 3 it is impossible to open the breech or to turn the locking-screw; but when for the purpose of firing the trigger is pulled the lug a of the safety-bolt A is withdrawn from the recess of the flange C, so that the breech maybe opened. In turning the locking-screw for opening the breech the curved flange O returns the trigger into the position of rest in the usual manner. IVhen in again turning the screw so as to lock the breech the lug a comes opposite the corresponding recess of the flange G,it is forced into this recess through the action of the spring What I claim as new ls- In an automatic safety device for breech mechanism of ordnance, the combination of the spring-bolt A inserted into a cavity of the breech-block, said boltA being provided with the lug a, toe c and with a push-button; the

breech-handle being provided with a recess adapted to re'ceiire the lug awhen the breech- In testimony whereof I have hereunto set handle'is turned to lock the breech; and the my hand in the presence of two subscribing trigger D With its projection. d being adapted Witnesses.
